    Description

      when a client gets evicted OST cancels its locks, but don't wait for its RPCs to complete. this way another client can get a conflicting lock and modify data, but then in-progress RPC from the evicted client can modify data as well. then we get a situation when the healty client holding LDLM lock has some data/state in his cache which don't match actual data stored on OST.
